Filed: 1993-03-18
Abstract: PURPOSE:To always perform sure door opening control by setting reference potentials of an IR sensor, for detecting IR rays emitted from the human body getting on-off a car, and an amplifier circuit to the potential different from each other. CONSTITUTION:A pyroelectric IR sensor element part 1 generates an output signal V1 relating to a temperature difference between the human body of generating heat and an ambient temperature within a detecting range, and this output signal V1 is input to a door opening signal generating circuit 6 through a differential amplifier circuit 2 for performing DC amplification of inverting and non-inverting this signal V1. After removing a noise component or the like by a filter circuit 3, the input is compared with reference voltage in a comparator circuit 4, and in the case of providing the input exceeding the reference voltage, a door opening signal is output. Here is set reference potential of the sensor element part 1 higher than the reference potential of the amplifier circuit 2 by a specific voltage, and potential of the output signal V1 is changed in a range of a potential level higher than the reference potential of an amplifier circuit 7.

Filed: 1986-03-17
Abstract: PURPOSE:To decrease sinkages generated in the molding part of a boss, a rib or the like by a method wherein a pin, attached to a thin sheet tube, is arranged detachably at a predetermined position in a cavity. CONSTITUTION:The shaft 2 of a ceramics pin 15 is penetrated through the center of a thin sheet tube 14 made of copper while the thin sheet tube 14 and the pin 15 function as one set of a pin P for a mold. The thin sheet tube 14 and the pin 15 are contacted closely with each other within a range permitting slip in accordance with the difference of the amounts of thermal expansion and are embedded into the mold 12 detachably. Resin, heated to the temperature of about 200 deg.C, flows into a cavity 13 through a runner 11 and is kept in a pressure. The resin is cooled through the surface of the mold from an instance when it is poured into the mold while the heat of the resin in the molding part Q of the root of a boss, in which heat is most readily reserved, is released efficiently into the mold 12 through the copper thin sheet tube 14 provided with a heat conductivity that is about 14 times of the same of iron. On the other hand, the deformation of the thin sheet tube 14 is restricted by the head of the ceramics provided with a thermal expansion coefficient of about 1/2 of the same coefficient of steel, therefore, the pin P for the mold itself may be extended only about 1/2 of the thermal elongation of a conventional pin.

Abstract: PURPOSE:To provide a two-dimensional and vivid X-ray image by allowing an X-ray generating means to emit an X-ray which is deflected for two-dimensional scanning, and sensing them with a light sensing means upon penetration through a specimen. CONSTITUTION:An electron beam EB emitted by a cathode 11 is deflected by a deflection coil 14 and put incident in spot form so as to scan the X-ray target 15 two-dimensionally. Therefore, the X-rays are radiated stringer in the direction of a photo-electron multiplier tube 20, transmitted through a sample 40 upon penetrating an output surface plate 16, transformed into visible rays by a scintillator 50, and is introduced into the multiplier tube 20. Photo-electrons from the photo-electric surface 22 are multiplied 23, and a corresponding signal is given to a frame memory 30. The address signal of this frame memory 30 corresponds to the output of a deflect signal generator 61. Because the data signal is stored in address corresponding to the position where the X-rays have penetrated the sample 40, the X-ray penetrative image can be stored in the memory 30.

CONSTITUTION:The non-developing part where the toner is not stuck is formed on the surface of the photosensitive body 31. The output voltage B in a white ground part and the output voltage in a black ground part C are respectively corrected by the value of the ratio between the non-development reference value A' which is the initial value of said part and the non-development output value A which is said value but is changed with lapse of time by the contamination of the density sensor and the change in the surface condition of the photosensitive body 31. The output voltage C of the black ground part is further corrected by the control value of the white ground part. The density in the black ground part and the density in the white ground part are thereby simultaneously corrected. The exact control of the picture density is thus enabled without being affected by the ground fogging of the white ground part.
